        - you could get different output from running tests via `prove` than you
do via running the test file directly, which could cause you to scrath your head
and go "WTF??"

I see Ovid mentioned in a later email that prove uses TAP::Harness instead of Test::Harness, implying that it doesn't have this problem, but I know I spent several hours a few months back trying to figure out just what the hell was going on, and it finally came down to _somebody_ flipping on -w unexpectedly.
